of the ball?

The final speed of the ball is 75 m/s. This can be calculated using the equation F = m * a, where F is the impulse, m is the mass of the ball, and a is the acceleration. Rearranging the equation to solve for a, we get a = F/m. Plugging in the given values, we get a = 15N/0.2kg = 75 m/s.

Answer 2

F dt = 15 = 0.2 dv

dv = 15 /0.2 = 75, agree
